application led April 11.5%,

Canada, and ALFRED JAMEs SALISBURY, of

the city of Toronto, in the county of, York, in the Province or' Ontario, Canada, have invented certain. new and useful lmprove ments in Battery-Cells, of which the tollen@ ing is the specification.

Our invention relates to improvements in 'battery cells and the object of the invention is to devise means forstrengthcning the wall structure ot the cell which will at the sar-ne time form means for holding the` plates and spacing members definitely in position within the cell and it consists essentially or. the following arrangement and construction of parts as hereinafter more particularly'ex- 2o plained.,

Figure l, is a sectional view of a battery cell constructed in accordance with our invention.

Fig. 2, is a plan View showing the top of the battery cell removed.

Fig. 3, is a sectional view through the battery cell showing the platesand spacers in elevation.

In lthe drawings like characters of reference indicate corresponding parts in the various figures.

l indicates the cell of the, battery provided with a top 2 and bottom 3. e indicates a tray located in the bottoni of the cell ,and

provided with cross bridging portions Al* which serve to support lthe plates" and spacers within the battery, cell. The/tray 4 fits the lower portion of the cell and serves also to form a reinforcement therefor as Well may be located a drain orifice at any suitable point. 5 and 6 indicate the opposing sets of battery plates which rest upon the bridging portions l* at/fthe bottom. 'l' indicate wooden spacers which intervene between leach pairof plates, such space being provided with notches 7 and in their upper Specification or" Letters atent.

edges. The plates 6 are connected together by a strap member 5c the terminal screw 5 through an oriiice in the top 2 of the cell, the strap 5X being provided witha shoulder 5 bearing against the lower face of the cell top, the nut 52 being threaded upon the stem against the outer face or the cell top. The battery plates 6 are similarly connected together by strap 6X provided with a terminal screw 6 having a shoulder 6 bearing against the lower 'face of the buttery top and a nut 6 bearing from which entends against the upper face,

8 and 9 indicate tie members extending across the cell from one side wall 1 tcthe opposite side wall l to which the ends of the tie members are secured by a suitable pass through the alined notches 7* and T", the tie member 8 bearing upon the upper edge of the plates 5 and the tie member-9 bearing upon the upper edge or' `the plates (i, the straps 5K and 6c bearing upon the tiel' members. lBy this means it will be seen that not-only are the side walls l and 1'of the battery cell tied together and thereby reinforced but also the plates 5 and 6 and spacing member 7 are held definitely in position within the battery cell thereby holding all the parts firmly toh gether 'to make a rigid unit.

From this description it will be seen that' We have devised a very simple structure whereby a battery cell may be lreinforced and the plates and spacing members held firmly in place therein. f

vln assembling weA properly group the electrodes e,rid"place the tie members in position in the notches previous to inserting in the cell. lil/ve then insert the grouped electrodes intofthe cell so as to rest on the bridges of the tray. After this is done the tie members are ement/ed or otherwise se cured at both ends thereof to the Walls of the cell, so that they are rigid and thereby hold the electrodes from both vertical and lateral displacement.

The cover of the cell is afterward placed in position und all sealing members and termmzlls are secuied and the 11d properly sealed.
